Appl. No.:

09/797179

Bruce R. Baker - Pittsburgh PA, US

International Classification:

G09G 5/00

US Classification:

715763, 715835, 715765, 715864, 715866

Abstract:

A computer device, such as a mobile phone or PDA for example, is able to access an application program or command, based upon selection of corresponding sequences of symbols. Such symbols can be polysemous in nature and thus be associated with a plurality of different meanings depending upon other symbols sequenced therewith. By utilizing polysemous symbols, a relatively large number of sequences can be developed and associated with programs and/or commands of the computer device, with only a relatively small number of symbols displayed. In devices such as PDAs and mobile phone where display space is a premium, such access to commands and programs can be invaluable.

Assignee:

AAI Corporation - Hunt Valley MD

International Classification:

H04B 1/16

US Classification:

4552261, 342174

Abstract:

A method of providing an integrated approach to automated system alignment is set forth, which may include in an exemplary embodiment: providing amplifier compression alignment, (which may include characterizing and/or compensating for a parasitic effect); providing continuous internal alignment of phase and amplitude of a synthetic stimulus instrument (SSI) output signal; providing external measurement port alignment; and providing transfer alignment of internal measurement paths. According to another exemplary embodiment, a receiver apparatus may include: a dual-channel coherent measurement receiver which may include at least one internal channel operative to measure time-division-multiplexed (TDM) feedback signals from each signal source of a synthetic stimulus instrument (SSI); and at least one external channel operative to make direct measurement at an external alignment port output.

International Classification:

H04B 17/00

US Classification:

4552262

Abstract:

A method for using a “B” channel of a dual channel measurement receiver as a transfer standard for power measurement, which may include in an exemplary embodiment: correlating measurements made with an “A” channel to measurements made with an RF Power Meter on one RF signal source, so that readings from the “A” channel are aligned to the RF Power Meter; aligning the “B” Channel to the “A” Channel (Transfer alignment of Channel B to the RF Power Meter), once the “A” channel has been aligned to read the same as the RF Power Meter; and using the “B” Channel as a transfer standard to measure all remaining RF signal sources in the system, on a time-line much faster than may be accomplished using a power meter.

US Classification:

4552261, 324 7612

Abstract:

A method for characterizing the effect of each step attenuator state, on phase and amplitude, which may include in an exemplary embodiment: activating each step attenuator state as the sole contributor to attenuation, and measuring at least one of a step attenuator amplitude contribution (SAAC) and/or a step attenuator phase contribution (SAPC).

International Classification:

US Classification:

345/835000

Abstract:

A computer device, such as a mobile phone or PDA for example, is able to output a message based upon selection of a corresponding sequence of symbol. Such symbols can be polysemous in nature and thus be associated with a plurality of different meanings depending upon other symbols sequenced therewith. By utilizing polysemous symbols, a relatively large number of sequences can be developed and associated with stored messages in the computer device. To aid a user in accessing a desired sequence or to aid in training the learning of stored sequences, for example, a category relating to at least two symbol sequences is fed back to the user upon pre-selecting a symbol; a theme relating to at least two symbol sequences is fed back to the user upon selecting a symbol and pre-selecting a next symbol; and/or a message associated with a sequence is fed back to the user upon selecting and/or pre-selecting at least one symbol completing a symbol sequence.
